Closes #410
This PR moves the command line snippet for PCI devices near the beginning of the QEMU command to support specifying PCI address 2.0 for e.g. passing through iGPUs which require this exact address.
Please note that this only fixes my issue with iGPU passthrough. Other VMs without passthrough and one with USB passthrough still work as before.
I'm really not happy with this solution, as if at any point someone else wants to set a low address to any other device after the passthrough devices, this problem will come up again. Ideally, this would be fixed upstream by QEMU.
